What is this symbol? (arrow with a 3 on it)

[JulieC]

I'm studying for my CLD renewal exam and am finding that I'm quite rusty.  The following VI diagram was in one of the online sample exams and I cannot figure out nor remember what the symbol in the middle is, the one in the middle of the for loop with the index, true, and the current array value going in.  Thank you!

That's our old friend the Feedback Node with a delay of 3.

It's a feedback node. Not sure what the 3 signifies.

Oh the 3 signifies the delay setting in the properties. I must admit I haven't used this node much.

Thank you.  I am almost positive I have not used it before, though maybe back when I was first learning LabVIEW and going through the tutorials.  I coded it up and played with it, the "3" is "delay".

Thanks Darin, I didn't find it on the pre-post search for "3 arrow".

I'm glad that I'm not the only one that couldn't figure it out.  I've never done any FPGA programming, so yeah, not a lot of real world usage for it.  It was comforting to read that some of the sample exam questions are there because they were rejected as real exam questions!  I've used LabVIEW almost none since I last recertified (shifting job roles, which are shifting in a direction that I probably will use it again).  My cert is going to go into suspend mode next week, which isn't too a big deal, but I'd like to get the recert over.
